The Portland Group, a wholly-owned subsidiary of STMicroelectronics and supplier of compilers for high-performance computing (HPC), has announced that Gaussian, an ongoing collaboration of scientists and academic research groups throughout the world, used PGI compilers to port a version of its flagship Gaussian 09 product to Intel processor-based Macintosh computers running 64-bit versions of Mac OS X.

PGI develops and markets C/C++ and Fortran compilers and development tools that are used by engineers and scientists. PGI Workstation compilers and tools enable building, debugging and profiling of 64-bit multi-core applications on the latest generation of Macs based on processors from Intel and running the Mac OS X operating system.

"A large percentage of academic and government HPC users rely on MacBooks as their mobile computing solution," says Douglas Miles, director, The Portland Group. "Now that Gaussian 09 is available on Mac OS X as well as on Linux- and Windows-based systems, these HPC developers can use and work on Gaussian 09 anywhere, any time using optimizing PGI Fortran and C/C++ compilers & tools.  The potential jump in productivity for these users is huge."

Gaussian 09 is the latest in the Gaussian series of electronic structure programs. It's used by chemists, chemical engineers, biochemists, physicists and others for research in established and emerging areas of chemical interest. It can be used to study molecules and reactions under a wide range of conditions, including those that produce both stable species and compounds that are difficult or impossible to observe experimentally, such as short-lived intermediates and transition structures.
